Specification of LettersEPatent.

Patented Jan. 526, 19%9.

Application filed July 1c, 1907. Serial No. seam.

To all whom-it may concern."

Be it known that I, iF iinnnro A; Bmiun, a

' citizen of France, residing at Birmingham, in

the county of Jefl'erson andState of Alabama,

have invented new and useful Im rovements in Train-Sheds, of which thei0 lowing is a specification.

particularly with reference to providing a structure, built on the unitplan'and therefore capable of extension in any direction,

"which possesses the advantage of perfect ventilation, .a'mple light,and an extremely low cost of :istruction and maintenance.

The pri1.-.. ple of construction, .upon which.

my invention is based, involves the provision of a series of parallellower decks which cover the train platforms between tracks and upperlight admitting openings which parallel the decks which cover the tracksand overlap the lower decks so as to leave ample space for the escapeofsmoke and admission of light while preventing rain, smoke, etc.,gaining access to the platforms. According to this construction theupper decks are supported above the lower decks and so positioned as torovide lateral protected ventilating and tracks and are distributedthroughout the shed at points where they will best serve to light therelatively low structure and free. it of all smoke and gases.

According to my preferred construction, the lower decks are eachsupported at the center by a single row of columns and act on theprinciple of cantalivers to support from their side edges the upperdecks. It is also an important oint of construction that the underfaceoft e up er decks which are disposed above the trac s should slantupwardly to each side, or, in other words, form deflecting surfaces forthe purpose of directing the smoke and gases iromthe locomotives towardsthe adjacent lateral ventilating openings'on either or both sides.

Myinvention also involves certain features of importance in counectidnwith the drainage of such sheds, particularly when constructed fromreinforced concrete. 7

My invention also involves other points in the construction andarrangement of parts which are hereinafter more fully described andclaimed and which are also illustrated in the accompanying drawingsforming a part of this specification, and in which line x :r of Fig. l.

Similar reference numerals refer to similar Figure 1,,represents avertical cross-sectional VlGW Of my improved shed. Fig. 2, represents avertical sectional view along the parts throughout the drawings. I Y

I have illustrated my invention in. a train shed constructed fromreinforced concrete.

Obviously, however, this is but illustrative as any other material maybe used and the 3 principles of construction involved may be adapted tovarious other structures. I

Referring to the drawings, the-platforms '1, between the tracks 2, arecovered-by the lower or platform'decks 3 of the shed. These decks areformed of thin reinforced concrete and are supported at intervals bycantaliver beams 4 which are formed ofstrongly reinforced concrete andsupported at their centers by columns 5; The side edges of the decks 3have vertical side walls 6 which )10- ject upwardly. The beams or arches7 which support the upper decks'S rest upon the ends .of the cantaliverbeams 4, each upper deck being thus supported bythe two adjacent lowerdecks and disposed so as to completely cover the open s ace between saidlower decks and above tie track or trackslaid between the platformscoverod by said lower decks. In the construction shown these beams areformed of reinforced concrete and are spaced any desired distance apart.

By referring to Fig. 2, it will be seen that a longitudinal ventilationand light 0 )ening 9 is formed between. the to of each si e wall 6.andthe overhanging sirleedge of the superimposed upper deck. This openingis calculated to permit free egress to the smoke and admit sullicientlight. Also the overhang of the upper decks are calculated withreference to the top of the adjacent side walls 6 to prevent rain orsnow being blown in through the openings 9. I thus provide a relativelylow structure which considered transversely presents a series ofalternate upper and lower overlapping decks with longitudinal protectedlighting and ventilatconnected by cross-braces 10.

' smoke beingdeflected towards the platforms.

The slope or angular disposition of the underfaceof the 11 per decksserves to deflect the smoke as we as the cinders from the locomotivesthrough the openings 9.

In structures of'this character which are built upon the .unit systemand therefore liable to be. extended .over a considerable area, thematter of drainage becomes :one

of considerable importancez It is my purpose to so drain the shed as toavoid any large accumulation of water-at any drainage point. To thisend, lmake the upper decks so that they drain towards.

the center and I provide a series of conduits il-formed in the beams 7and leading from the center line of each upper deck down through thebeams to discharge upon the lower decks which in turn are drained byconduits 12 leading down through the decks 3, cantalivers 4. and theirsupporting columns 5 to a drain pi )e 13 below each platform and runninglengthwise thereof- I prefer to arch the sections of the decks betweentheir supporting beams 4 and 7, as seen in Fig. 2.

in Fig. 1, I show the shed with the decks designed for single and doubletracks. Obviously the side edge of the outside upper decks will receiveappropriate supports until it is desired to add another platform orplatforms and extend the shed l aterally'to cover them when any desirednumber of upper and lower decks may be added. Also-the shed'may belongitudinally extended at will as it is, as a whole, entirelyindependent of anyunity of design and structure. It is in fact asectional or unit system of overlapping upper and lower decks whichprovide a covered and protected shed which is better lighted andventilated than the vast structures now in use and is also free from thenil-any serious objections-which practice has shown to exist with regardto such struc-' tures.

A feature of considerable importance in' gases from the smoke andrequire constant;

' attention.

Having thus described my invention,

- what Iclaim as'new and desire to secure by Letters Patent, is:-

I I

2. A trainshed for protecting tracks and their platforms'compnsing lowerdecks parallel with and adapted to cover the track platforms, and upperdecks supported above the lower decks and disposed so as to cover thespace between the'low'er decks and provide longitudinal protectedlightiand venti- 1ation openings between them and the lower decks.
